Finally, the wait is over. Here you are ~ the very first Android 2.3.5 Gingerbread firmware for Samsung Galaxy S II officially (leaked). As usual, this is Europe firmware for Samsung Galaxy S2 as Europe is always the first region to get the latest stuffs. But it is okay to install it on other region Samsung Galaxy S2 as long as it is using the very same hardware GT-I9100. Okay, let’s find out how does this new firmware XXKI3 performs…

Android 2.3.5 XXKI3 for Samsung Galaxy S2

Wow… Quadrant score at 4k. Well done, Samsung. There is no CF-Root for it yet. But I managed to root it with CF-Root for XWKI4. Hmm… Any other new features on this XXKI3 release? You let me know…

Quadrant scoreTouchWiz LauncherSoftware information

Note – This is a WIPE version. It will delete all applications and data on your phone. Or you can try Frankenstein non-wipe version at XDA.

Sorry, I am not sure because I don’t use Samsung Kies. I heard people complaint that it is not stable some times. I prefer to use Titanium Backup.

jocom6036

as long as u pc can detact u phone, u can still used samsung kies..

>This is a WIPE version. It will delete all applications and data on your phone
all applications including all samsung stock apps?
what is the easiest way to back up all apps and data?
can I simply copy all of them to my PC before I update?
Please advise.

Thanks. Little bit of topic: Does anyone know if there is any homebrewn firmware that can be applied to the Chinese phone? MIUI or Cyanogenmod for instance? Missing essential applications from Google like Market.

I have been following your site for some time, but so far i didn’t see any post saying bug regarding galaxy s2. I have galaxy s2 from the day it launch, and i facing so many bug seen. I have done read thought many site and i find that update the firmware will solve the problem. the following are my galaxy s2 bug:-

1. 3g/2g signal = often drop and can’t go back online. need to turn to flight mode than reverse back.
2. most of the game hang, done search on net and it say is due to soundpool error.
3. voice echo when call to user, user can heard echo sound which very bugging them

my question are :-

1. did you face any off this problem before?
2. if yes, did the update xxki3 solve the problem?
3. if no, than i guess i have to send for warranty than.
4. what sim card did you use? 64k sim? (my are old sim from digi 64k)

sorry for posting this long but i really can’t take it anymore with this bug. and thanks in advance. by the way, love your site 🙂

jayce i tried to install darky rom and i did’nt like it so i go back to k13 and wipe the data/application and cache, but i’m in trouble all my application was deleted but take note i do back up using cwm and now i’m trying to restore using cwm also “restore existing back-up” and “i reboot clock work mode recovery” i see my old back up in sd card but i cant update go through this to restore all my application…how can i get back all my application.

1. It is leaked official firmware from Samsung. But can’t upgrade through Samsung Kies.
2. Use CF-Root.
3. Yes, this firmware does not touch all the contents in sdcard. But no harm to make a backup copy to PC.

ricky

cheers man for the help this is my first android phone so im a newbie can you tell me what are the best things to do now that i am rooted what apps to install etc

and also the music etc want on a sdcard they were on the phones internal memory

jr

PDA:KI3 / PHONE:KI3 / CSC:KI3 (XEO) this is what many sites are saying is the official firmware
when i connect to kies it states PDA:KI3 / PHONE:KI3 / CSC:KI3 (KOR)<<<<< the letters here are different does that matter

Try these…
– Turn off SGS2.
– Press and hold down Volume Up + Home + Power buttons at the same time.
– Release all buttons when you see SGS2 Logo.
– Android system recovery will be loaded then.
– Select wipe data/factory reset. Then Yes.
– Select wipe cache partition. Then Yes.
– Reboot system.

Doomed

U dont know, but u saved me. thought my sgs2 got bricked after i did a custom rom and my phone started this unending restart thing. as a final try i did above thing and all set to go..
Thanx a million

dinker

Yup it worked after i done what u said. thanks a lot. u r genious.

Hi Jayce,

I only got a quadrant score of 3306 after updating to xxki3 (stock, unrooted). Why is there such a big difference to the score you obtained above? Thanks in advance.

I was upgrading my S2 firmware to 2.3.5 as mentioned but after clicking start button on odin3 there was no progress bar visible even after a long time. So I unplugged S2 and after that neither i can start it nor it is booting to any mode. In other words it’s just dead. Can you tell what’s wrong?

Yes, warranty void if you using XXKI3. You need to restore back stock firmware XWKF1. I told you already, right?

Beginner 85

But i dont know to do that,can you give me any shortcut or instruction maybe..? plz reply.. It’s really frustrating.I can access internet or open youtube but i cannot download any apps from market android..Plz reply asap..

1) I bought ma phone from India, its xwkf3, I updated to ke7
after ma succesful update I went to ma “about phone” and checked if there was any higher official update available, and there was, so ma phone started to update and after the completion ma phone came back to xwkf3. So I wanna know what happen? did i downgrade ma phone and again updated it?

2) About this update here 2.3.5 which is leaked, is it safe to do it? or shall I wait for the official realease coz they might add somethin more to it? if i update from “the leaked” will i be able to upgrade it officially after that?

please help.
very confused.
I love this blog. Thanks for helping us android lovers.

2. I tried it. No issue so far. The version here is a leaked version. Can’t upgrade through Samsung Kies. But you can try the official one at XDA. That can be upgraded.

Raviraj

hey joyce,
thanks for the reply,
I jus learned that there is a 2.3.7 upgrade?
is it out yet? or it jus a rumor?
and please send me a good official link (xda) for 2.3.5 upgrade or 2.3.7 whichever yo thimk is the best. I’m never sure where to really download from (i’m skeptical). I want ma phone with the latest updates.
help! please.
thanks.
🙂

Not sure about 2.3.7. Anyway, you can get the latest firmware at XDA. Link in the post.

Raviraj

I am not able to find the link brooo!! please send it, i am waiting to upgrade ma phone to 2.3.5 official!! cant wait….
🙁
also shall i download darkysrom2? is it a cool tool? do i have to root ma phone for it?

These packages have the new bootloader removed and repacked with the old ones so you can safely reset the binary counter with a Jig. 🙂

If you’ve already flashed a full package from elsewhere and cannot reset your binary counter using the Jig just flash this package in the PDA or Bootloader (Yes both will work) section of Odin to replace the bootloaders and then you can reset the counter:http://www.multiupload.com/LQQBRQVJUD

Samsung does not provide change log between versions. So you need to test them yourself to find out.

FYI, I am using custom firmware based on XXKI4 now. 😉

Raviraj

I mean its a sgs2 I9100 from India, it says made in China. Yo know I am so excited to see the 2.3.5 update on ma nu phone but I have never been so confused in ma life before. I think I am gonna download this XWKI8 thingy coz it sounds latest to me, unless the great jayce has somethin else in mind.
:(((((
:((
help me father!! show me the light

CSC is the consumer software customisation and is specific to geographical region and carriers. It contains the software packages specific to that region, carrier branding and also APN settings for data connection, MMS etc for your service provider.

Hey Jaycee,
I have some applications which are not purchased from the market and I wanna upgrade them without making the purchase. Is there a way to that Mr. Android Genius?
Please help!

Galaxy s2

Raviraj

I didnt get any link. please send it again.
🙁
please copy paste!

Helloo jayce
im from indonesia . actually i just upgrade my firmware from xkg3 2.3.4 , to this firmware 2.3.5 . I found out it drained my battery very fast.maybe it will last just for 6hours.
My question is :
I want to downgrade again to xkg3 2.3.4 ,should i do some procedure or i just do like when i was update the firmware?thanks jaycee

You need to wipe data and cache when downgrade. Installation is the same.

ezzo

Hmm .just wipe data and cache then?ok!thnks jacyee.i will try

Hello Jayce,
This is a great site, congrats!
I placed an order @ Amazon UK for a SGS2 a few weeks back but it turned out that it’s from Hong Kong.I think it’s not a big deal, but some languages I need is missing (Hungarian), which can be found in the EU versions.
Of course this can be fixed by flashing an EU ROM to the phone, however, I read that the firmware version I’m flashing should match the phone’s firmware. On another site I also read that it’s ok to flash ROMs from a different region as soon as the hardware matches.

Would you please confirm that:

1) flashing a ROM from another region should not result in my device being bricked (unless something goes wrong during the flashing procedure), the worst thing that could happen is that the device becomes unstable but I should be able to flash another ROM.

2) SGS2 devices from different regions should have the exact same hardware (right (?)), so my device should be able to run basically any ROM out there (?).
Details of my phone:

Baseband version:
I9100XXKG1

Kernel Version:
2.6.35.7-I9100ZSKG2-CL361136
root@ubuntu #6

Build number:
GINGERBREAD.ZSKG2

I still have the option to return my phone to the seller, but if you think there’s a way I can use an EU ROM with my phone, probably it doesn’t make sense…

Yes, no problem to flash other region firmware as long as it is same hardware model I9100 (except for China I9100). Hong Kong SGS2 model is the international model. I am using Europe firmware on my Malaysia unit now. 🙂

mich

Woww, thanks for the quick response.
Great, then sending the phone back doesn’t make too much sense…

@Raviraj: You can only use that particular telco SIM card only if the phone is network locked.

Raviraj

hmm… I updated ma phone with XWKI8 successfully and its workin well on ma sim, so i guess I meet their expect.
thanks.
I donn see any difference from 2.3.3 to 2.3.5 yet. but there is one thing I’m hating, I use tethering and portable hot spot alot and this upgrade doesnt allow to make any changes in configuring Id password –
its,
Network SSID – AndroidAP
security – WPA2 PSK
password – 823e3d04966
which is unchangable, cant change is ssid name of password of security type. it changes temperorily, I use “open” security in ma room.
it really sucks. I am irritated.
is there anyway we can change it?

ok so yo are using XXKI4 right? does it have this problem? i think i am also gonna upgrade it to xxki4 if it doesnt , i tried to post ma problem on xda forum but it say something about posting 10 comments first only then i can quote a post… uff!

Depend on the kernel that you plan to install. There are CWM and TAR format. Check with Kernel developer for more info.

Raviraj

I upgraded ma phone to XXKI4 but the problem mentioned above still stays… i though yo said that XXKI4 firware doesnt have this problem, yo said “no issues on XXKI4m wrong, there is. do somethin i want to use ma hot spot as “open” without any password.
help!! jayce!!

Does the new firmware fix the problem on low mic volume, most of the people i called using the headset mic complained that my voice is very far and low. I have sent my phone to the service center and the service tech informed me that he has changed the mic and etc but still facing the issue. I have read on the XDA forums that firmware upgrade solves this issue.

Is the problem caused by your headset? I don’t have low mic volume issue even on stock firmware.

Joe

I’m not sure, if they have changed the mic and problem still persists than i think it could be the firmware. Only have this issue with headset, if i’m using speaker or Bluetooth no issues. I have read in XDA forums some people have face this problem and some had replacement to fix the issues and other firmware upgrades to 2.3.4. I just upgraded my firmware to DXKI1 which is still on 2.3.3 but it did not fix the problem. Wondering if any other Malaysians is having this issue as well.

You can try to upgrade to Android 2.3.5 if you want. Not sure it can fix your issue or not.

Joe

Yes sorry its the phone internal mic not the headset, i will try to update and see if it fixes the problem.

Dear Jayce,

I updated my S2 with GT-I9100_XEU_I9100XXKI4_I9100XEUKH2_I9100XXKI4.tar (2.3.5 XXKI4 Release). I have used Odin and it is just a firmware update. Not Rooting.
So in case i have to go to Samsung support all i need to do is reset everything and update again with the latest India Firmware. Is it correct? or Will i need the USB Jig? Please advise.

I have updated my sgs2 to xxi3…. Probably i downloaded this fw from android advice ( i don’t remember exactly, it came probably from samfirmware.com )…. Its camera display has gone darker as compared to one i previously had (2.3.3)….Is it normal ? Can i again flash it with xxi3 using your link ? How can I do it ?

if i wanted to get back to 2.3.3? will i have to use only pda file or all three files using odin ?

2. In case, i also wipe cache and data……should i also wipe partition ?

3. What is clockworkmod recovey ? and how is different from android recovery ? I have android recovery on my cell…………how can i bring or install clockworkmod recovery ?

4. I don’t have an sd card …………can i still use titanium back up ?

I am sorry for these too many questions……….but these emerged in my mind after reading various threads after reading in your this very informative blog…. Few things are too technical for me to understand as I am a beginner………….Kindly guide ..

Hi Jayce, In case you have mentioned the advantages / benefits of 2.3.5 over 2.3.3, can you please paste the link. I have a Samsung Galaxy S2 which runs on 2.3.3. Looking forward to upgrade to 2.3.5. Your Blog is great :-)..

hi jayce………..do we need to root our cell as well after flashing with kki4 or is this inbuilt ?

I have just flashed my cell with this new fw but how is different from xxi3…….? i couldn’t find any difference at all…………..even my all apps and settings are intact……..in about phone ,how ever information is changed to baseband 1900xxki4.

In one of your threads………which now I am very fond of browsing as they add wealth of some very useful and “honest” stuff to my knowledge…………I read that you were using some checkrom revolution hd rom ! I was just wondering ,you are using xxki4 or this above stuff………..Which one is better.?

My SG S2 is 2.3.3 DDKE4, XWKF3. Also I had the low mic volume problem and pink spot in camera, no noice reduction cancellation button too. An yellow tint in left of the screen from top to bottom. Please tell me which update fixes these all problems. I found these are common problems for all s2 users.

CheckROM RevolutionHD v1 is a custom ROM based on XXKI4 firmware. It is like enhanced version of official XXKI4 firmware.

kamal

so now as I have had xxki4 official firmware…………I can further update with checkrom revolution hd too ???? and if i don’t have xxki4, I can’t put checkrom on ? Is this what you want to say……..?

If I have understood you correctly, please tell me how to install now this checkrom………Please give links………..

Plus , today I ran antutu benchmark on my cell ( you have mentioned it somewhere in your blog), and I got pathetic 5921………and I was no where even in ranking ………..What does this mean? situation was not so bad on quadrant where my cell was at top after all…..

Oh I see…………..dear……I didn’t even know of this asus transformer stuff…………It seems to be something really powerful…………….So take my words back…………I was really wondering what is this which excelled my sgs2…………..but this is tab ,not a mobile, right ?

Jayce..
I want to claim my warranty
so iwant to unroot change to my original firmware
my question are
When i downgrade my firmware to its original .do i still need to do the unrooting stuff again or its already unroot?
And if you need to unroot again..how?my firmware nw are xxkg3. i want to go back to my ori rom which is are dxkg3..
Thnks jaycee.. sorry to many questions..

Updated from 2.3.3 to xxki3 and then to xxki4 official ….following your guideline…..Now there is a problem……….sometimes “message ” application doesn’t just open and a small window pops up saying that it will force close and sorry ……….every time I try to open it, the same happens unless I switch it off and then reboot………..Only then problem resolves………..Besides I have “buddy” widgets” on my home screen with their photos……..during such crashing /hanging, these widgets also go blank with no photos……………..

Please shed some light , why is this happening……Is it fw or some other issue……or is just normal hanging of this phone. ? Please suggest some solution………..

Nope. It is scratch resistant but still can be scratched. So do be careful on handling it.

kamal

one more thing……………usually while playing games, in excitement, one tends to press buttons or touch screen ins galaxy little harder…………..can it spoil its touch sensitivity or it’s strong enough and purpose built to bear such stress ? how careful should we be……?

I removed my cache/data as you advised to overcome force closure issue with my cell…………to remind you , I updated it from 2.3.3 to xxki3 and then to xxki4 following your procedure……….Sometimes while opening any application, that doesn’t open and rather get stuck and then messages pops up saying that sorry and now it would force close………………
I repeat …………..is it normal “hanging ” with such phones………….if not , should I downgrade to original fw or update to some new……………..????? Please suggest and guide >

I downgraded to original version that is 2.3.3………..GT-I9100_ORA_I9100BVKG3_I9100BVKG2_I9100ORAKG3.TAR was the file………….before downgrading………i wiped data /cache as advised……………………now there is strange problem……….phone is just not starting…………there is logo of orange company then flashes the “S” of samsung on the screen and that’s all………….it repeats again and again…………..what should i do now ?

thanx jayce……………one last thing…………….after downgrading………….my kernal version is still slightly different from what i originally had ………………like b4 , I had 2.6.35.7-19100XWKDD-CL161513 root@DELL 103#2 and now i had 2.6.35.7-19100bvkg3-cl344296 root@DELL103#2.

does it make any difference and if it does, how can i find out original kernal .?

XWKDD is not original kernel for BVKG3 firmware. BVKG3 should be the original kernel.

kamal

thank you so much jayce .

kamal

hi jayce.

I reverted to stock fw which I had to find out on xda developers site as I didn’t have any back up. Assuming that , it was my original stock fw,I flashed it……………It was GT-I9100_ORA_I9100BVKG3_I9100BVKG2_I9100ORAKG3.TAR…………. Now please suggest some way to root it……….I mean what is ,in your expert opinion closest CF match………

2. When I bought cell…………..it already had a yellow triangle while booting and a superuser box in the menu…………though when I installed titanium back up app, which demands root access..the application didn’t run saying that cell was not rooted……….So was it rooted or not ?? and if it already had yellow triangle, did it mean, it was a used cell ?

3, Can I back up the firm ware and all the operating system on removable memory card, not the inbuilt SD card……….. and then can I restore this on my Cell using this removable memory card in another mobile ( SGS2 )???

Please guide dear, especially your opinion about this last point will be invaluable to me …

jayce , another thing…………………..how to know ,I have an sd card, I mean ,is there internal one ? my task manager in ” storage” shows sd card = unavailable space…………so I assume, it’s not there . If so, then I can not use CWM ?

my device ( task manager ) is just showing system storage 238mb/1.97gb and usb storage 2.34 gb/11.50 gb ………..In sd card…………there is 0.oob/o.oob………………..So is there no internal one. ?and how much is this total memory ?

A custom firmware / kernel was installed on your phone. So you got yellow triangle.

kamal

dear jayce…………….how do you compare sgs2 with new arrival samsung galaxy nexus……………

I recently dropped my sgs2 on floor…………..is their any thing , i can check my phone with ………like I used some z device test….that showed it ok except showing temperature sensors………….any thing else in your opinion ?

dear jayce……………….Initially I updated my cell to 2.3.5 using odin……………then I reverted to 2.3.3 using official fw given on xda developers site…………I also wiped all cache data as you instructed……then again I upgraded back to 2.3.5 but this time using kies and officially…………So now it has official fw of orange………..

Still my buddy widgets sometimes suddenly go blank and application fails to open displaying “sorry” message and informing me that app will force close……………..Is it normal “hanging” of cell or what ? What should I do ????????????? I usually reload my pics on buddy widget after every such incident……

hey whats up ma android god!
is it time that i can upgrade ma sgs2 with ice cream sandwich?? is the good firmware out yet?? is the leaked one out yeat?? as is good or should i wait for the official version??
holla back.

happy new year jayce……………….wish to continue to have you as mentor this year as well…………thanks for everything… and look forward to more 😉

Hi Jayce

I am new to rooting and flashing my SGS 2 , just wanted to know wat would be there best ROM to use for my phone to make it faster and better,

Hi Jayce I have a GS2 with Firmware I9100UHKG4 and Kernel 2.6.35.7-I9100UHKH1-CL463316se.infra@SEI-21#2. I can’t find unsecure kernels to root, please help me what can I do?? Can I just flash any insecure kernel?? Thanks.

but dear while mentioning specs of sony xperia………….they seem to take an edge over sgs2 like 1.5gh dual core ……….12 mp camera , probably better resolution and latest. In various head to head comparisons…………sony xperia is being rated equal to sgs2 or slightly better…………how then are they one generation behind ?

JAYCE we have iphone 5, sony xperia s , htc one x and samsung galaxy s3 all locked in very tight competition in 2012………Their head to head comparisons are very impressive and close…………….what will be your choice based on their specs , some out and some still rumoured ?

Sony Xperia S out. I bought HTC One X. Will buy SGS3 too. Will buy iPhone 5 only if have new CPU (don’t want A5X).

kamal

hi jayce…………..after very very patient waiting ………finally updated my sgs2 to 2.3.6 from orange through kies…………….but little disappointment,,, rather lots of it……..it took me three hours and i am just flustered , what is the difference between 2.3.5 and 2.3.6……..it’s just the same……….isn’t it ??????

Just some bugs fixes if not mistaken. I can’t notice the different myself too.

kamal

jayce…………………have you found kindle fire better than ipad 3…….i was just looking at both……….and this is first time, i started learning about tablets and their specs…….Being a firm believer about your expertise and exquisite choice, i was little surprised that you went for kindle fire while on papers i pad 3 is far superior………..

Hi kamal, I am also not sure which CF-Root can you use. Try to consult others at XDA website.

kamal

jayce…………….following your advice I posted this question at xda forum…………..and someone suggested me to use
SGS-XX-OXX-LPB-v5.2-CWM5 by chainfire……………….what do you say ? If it didn’t work , would it spoil my phone ?

thanks jayce for your help and guidance………..sgs3 released…………what do you think ….are you buying it ? Isn’t it a bit disappointment compared to speculations about it. how do you compare it with htc one x ?

And please tell me one more thing that… as I wont be upgrading ma phone though Kies … but this will be an official Indian ICS upgrade… so will I be able to get 4.4 or 4.5 and on… upgrades later through ma mobile carrier?
I hope I made ma point clearly comprehensible to yo.

The official firmware (other region) has India CSC but it is not released in India officially. Just check with Samsung Kies and you will know.

Raviraj

I’m jus waiting for the official kies update… please lemme know as soon as it realizes…
🙂
I downloaded the firmware which was said to be the official firmware for India, it was on XDA. They said that it was gonna be officially launched by kies.
Its alright, there are 2 small problems, with wifi on-off and I cant change the wallaper on ma home screen… it force closes.
🙁
I’ll wait till ya gimme a green flag waving. 😀

I’ve updated from Kies the official ICS 4.0.3 version. I never rooted or flashed my galaxy s2 so far. This official update that I’ve installed on my phone is very buggy (Twlauncher crashes all the time, some times the touch screen is not as responsive as it was with Gingerbread, battery draining a lot quicker, etc.) and I have to do something about that. My questions are:
1. Can I downgrade to the previous official firmware I had installed without rooting the phone?
2. If I do that (Question 1), my warranty will be voided?
3. Can you give me the link to download the latest official Gingerbread? And some quick instructions on how to install it on my SGS2?

P.S: Please note that my phone has never been rooted and/or flashed. Thanks.

Hi Raviraj, I did not try out other Android 4.0.4 firmware on SGS2 yet. You need to try out yourself to find out…

Raviraj

Ayyy!! Come on… this is not fair… yo are the android guru here…
Yo need to do it first and then guide us if we should or not… im reading on some websites that it has lot o bugs… so I came to yo…
Help
Enlighten us! Please!

Hey jaycee!!
Yo have still not informed me about 4.0.4 for Samsung galaxy s2 weather its ok to upgrade to it or not…. and now jelly bean 4.1 is available too… is the review good for jelly? Is it time to upgrade? 🙂

Sir, i have bought new SGS-2 and by mistaken i install custom rom which was name tim… after that the phone battery timing goes only 25 minutes. and also ther are some bugs. now i want to download from your given link the stock rom for S2 but there is ilivid video down loader. i have tried many many times and many different websites. stock rom is only at your web. Please provide me any link where i can easily download the stock rom. its just 4 days ago i bought it n don’t wanna lost it so early.

I have checked all version there are up to 4. (4.0, 4.1) etc. I have downloaded the Odin3-v1.85 From your web but can’t download the Rom, every time ilivid down loader appears. I just need now 2.3.5 stock rom for Samsung Galaxy S2. Please if you can assist me. or i can give you remote access of my PC its 24 Hours connected you can access it any time if you like.
